What is RETA
RETA also known as Retatrutide is a novel triple agonist targeting GLP-1, GIP, and glucagon receptors. This new-generation peptide is under investigation for extreme fat loss, metabolic acceleration, and advanced appetite suppression. Due to its comprehensive action on multiple pathways, RETA shows superior outcomes in reducing body fat, managing blood sugar, and improving energy expenditure. For athletes, it may represent the next frontier in weight management and performance preparation.
Benefits of RETA
– Extreme fat reduction and metabolic acceleration
– Enhances energy expenditure and calorie burn
– Dramatically suppresses appetite and cravings
– Improves insulin sensitivity and glucose metabolism
– Potential to improve liver and cardiovascular markers
How to Use RETA
Previous Research Dosages Used: Clinical studies assess weekly doses starting at 2mg and increasing to 8mg or more, over a 12–24 week period. Research shows significant reductions in body fat, waist circumference, and fasting glucose levels.
Frequently Asked Questions
1. How is Retatrutide different from Tirzepatide?
Retatrutide acts on three receptors (GLP-1, GIP, and glucagon), potentially offering more fat loss and metabolic activation than dual-agonist compounds like Tirzepatide.
2. Is Retatrutide suitable for athletes?
Yes, it’s being explored for cutting, appetite suppression, and improved body composition in high-performance athletes.
3. Are the side effects worse than other peptides?
Some users report stronger appetite suppression and mild nausea. Gradual dose escalation is recommended to minimize discomfort.
4. Can Retatrutide help with insulin resistance?
Yes, it improves insulin sensitivity and fasting glucose metrics significantly.
5. How long does it take to see results?
Noticeable fat loss and appetite suppression can begin within 2–4 weeks, with peak results around 8–12 weeks.
6. Does Retatrutide require PCT?
No, it does not interfere with hormone production or require post-cycle therapy.
7. Can it be stacked with growth hormone or SARMs?
Yes, it is often used alongside peptides like <NAD+, MOTS-c, CJC-1295 or SARMs during aggressive cutting protocols.
8. What diet works best with Retatrutide?
High-protein, low-carb diets maximize fat-burning and minimize muscle loss during research cycles.
9. Is it injectable or oral?
Currently, all research is based on injectable administration once per week.
10. Is it approved for human use?
As of now, Retatrutide is for research purposes only and not approved for general clinical use.

How to Reconstitute
All peptides need to be reconstituted using BAC Water (Bacteriostatic Water).
In most case the ideal amount is 2.5ml for GLP1’s (Tirzep, REta SEMA etc).
Heres is a handy video to explain how to safely reconstitute your peptide. Important, DO NOT shake the peptide. Roll in between your hands per the video.
If your more interested in wanting to see how and/or where to inject, fast forward to the 6.03 mark of the video.
Dosing Schedule
Below is a common and recommended dosing chart and timetable for RETA & TIRZEP used by most reserachers in the weight loss field. One needs to start off slow and lay the foundations (even foundations are progress) but the real changes appear around week 9 onwards (this is akin to the roof being put on a new house – it starts to take shape).

As an example of what these doses would look like in a syringe, we have attached the examples based on 2.5ml of BAC Water being used to reconstitute the GLP-1 peptide.
WEEK 1-4 (2.5mg per week)

WEEK 5-8 (5 mg per week)

WEEK 9-13 (7.5mg per week)

COA's & 3rd Party Tests
The Magical COA’s and 3rd Party Tests that everybody wants to see.
We as a family company want to shed some light on the whole COA’s mystery. 99% of all COA’s and 3rd party tests promoted by companies are totally USELESS, MISLEADING and in many cases fake and are used purely as a marketing tool to make people feel comfortable. WE DO NOT operate like that. We will tell you how it is and if we lose business becuase of it, the company is prepared to do so. but we hope with our honest approach we can shed some light on your COA’s query.
Let us explain to you as a company on the inside why COA’s and 3rd party test are basically useless.
We believe we are the only company in the peptide space, trying to make consumers aware of this fake marketing tool of the COA’s & 3rd party tests. We wont even discuss how easy it is using software like CANVA to change any COA to suit your own marketing needs. We did it ourselfs in 5 minutes. Its so easy it scary !!!!
While we do have COA’s and occassional 3rd party tests, we use these exclusively in our own lab for in house production quality testing and pre & post raw material purchases. They are not on the website because it’s all an illusion and fake information to mislead consumers into a false snese of purity security. I mean if there trying that hard to convince you, then id be thinking about that fact actually. We have seen 1 company promoting COA’s and three (3) , yes three (3) indepenednent 3rd party tests on all their products.
Our company being a family business has a strong policy of transparency and a COA is not that at all, unless you are buying 1kg or more of raw powder and then onselling that powder or using it yourself. This is the ONLY time a COA has any validity, let us explain why.
COA’s we don’t advertise, like other companies do, because they are totally MISLEADING.. The majority of all COA’s are misleading. It’s a hard industry to navigate, a bit like the vitamin industry. The problem with COA’s is they are never linked to a product vial by batch number. Reason being peptides being freshly made every 3-4 months, sometimes sooner, it is logistically impossible to link a batch number to a COA and then get tests done, new vial labels made, printed, and put on vials and then advertise it and put out to market to sell. By the time that’s all done the batch is already sold out and a new batch of peptides is being manufactured. Batch coding only works for something like a big Pharma when they are producing 1 million runs of something otherwise its not viable. COA’s are really just an illusion for people’s peace of mind… but it doesn’t tell you anything, just think about it logically.
We can show you a COA for a product (i.e: RETA) and it will show 99.64% purity. Which is great. But that is the test result for that 1 vial only. All tests with COA’s are done on a 1 vial bais only at acost of around $350. So with that test result, does that mean every other vial they are selling is of the same purity. Nobody knows because the industry is not regulated, just like the vitamin industry isn’t either.
There are a few companies that have batch numbers on their vials and they advertise that fact (red flag No# 1), but you visit that same website in 6 months or buy off them today and buy again in 6 months the same product and it will show the same batch number on the vial. We know because we have done the exercise. Once again an illusion for consumer comfort. We won’t mislead people.
Sorry we cannot give you the YES answer you’re looking for, but we are giving you the truth and wish to open your eyes on the whole COA marketing game. We hope that this explaination gives you a bit of understanding.
We are a family business and we don’t w ant to mislead anybody hence we will not advertise COA but I assure you we make sure every product is no less than 99% purity or it doesn’t leave our lab.
In finishing, to be fair the majority of peptide sellers (good ones) will all have 99% + purity. It eventually comes down to who you feel comfortable buying from. We have huge repeat clientele because our products are premium and we offer great customer service.
Good luck with your decision making, we know it’s a tough one, but we hope you’ll consider us.

Reta is grouse! Great comms and delivery from the team. Will be back for sure.
Steph (verified owner) –
This works. As a lifetime, off and on dieter, I have to say this gave me dieting superpowers, 12 hours after I started. I started in the evening and woke a different person. Do some research, this is also has mega anti-inflammatory properties which I had no idea about. I suffer with fibromyalgia, or at least I did before Reta. I got out of bed for the first time in years without all the moaning and groaning. In regards to eating, I was a constant grazer, but now I look at the clock and hours have passed and I haven’t felt the urge to eat. All of this from a 1mg dose. Yes, I was super cautious. I read you should have a dose every 6 days, but do your own research. So far I have experienced zero negative side effects. I am so glad I still have all my favourite pants and jeans, and the thought of wearing them again is the best.

Cat (verified owner) –
I’ve taken Mounjaro in the past and this is next level. Weirdly seems to target fat loss better. I’m on less than the starter dose and that’s enough for me.
Mark Jolly (verified owner) –
Excellent !
I found this vial very good quality
I called them twice for some advice and he was more than happy to answer my questions
Will be buying some again soon
Jo (verified owner) –
I’ve had such a great experience with Reta! The whole process was so easy to understand, the website was simple to navigate and really informative, and the product itself has been fantastic for maintaining my weight, controlling cravings and especially reducing food noise.
But what really stood out was the incredible customer service. My order was delayed by Australia Post and I urgently needed it before travelling. The team went above and beyond and actually hand-delivered my order to make sure I received it in time!
The customer service has honestly been second to none. Amazing product, amazing team and an all-round fantastic experience. Highly recommend!
